Yesung met with Siwon, Donghae, Changmin, and Yunho, who are currently serving their mandatory military service, at the 'U Clean Concert' on May 27. He shared the photo above on Instagram with the message, "U Clean concert #Whistle #superjunior #tvxq." The 'U Clean Concert' is a festival that supports an internet space that's safe and without bullying for teenagers.

In related news, Donghae will complete his army service in July, while Changmin will be discharged this August. Yunho was discharged this past April, but he joined Changmin and Donghae as part of the military entertainment unit Whistle.

Yunho - still working even though he doesn't have to. This man is just too much! I can't wait till August. Army life seems to be doing these guys just fine. I just happened to stumble across Donghae and Changmin in the military "Pick Me" parody yesterday and couldn't stop laughing (apparently Changmin was trying real hard not to laugh too).

how handsome those guys can be???? i saw their "Mirotic" performance and notice they look so relax and happy, i'm looking foward to see them in TV again. BTW Yunho came back but it's like he's not, maybe he is resting waiting for Changmin
